This pr resolves some discrepancies in verification during `validate` in `DXILRootSignature.cpp`. Note: we don't add a backend test for version 1.0 flag values because it treats the struct as though there is no flags value. However, this will be used when we use the verifications in the frontend. - Updates `verifyDescriptorFlag` to check for valid flags based on version, as reflected [here](https://github.com/llvm/wg-hlsl/pull/297) - Add test to demonstrate updated flag verifications - Adds `verifyNumDescriptors` to the validation of `DescriptorRange`s - Add a test to demonstrate `numDescriptors` verification - Updates a number of tests that mistakenly had an invalid `numDescriptors` specified Resolves: https://github.com/llvm/llvm-project/issues/147107
